.To a/ZZ whom it may concern: Y

' Be it known that I, JOHN JANssoN, a subject of the King of Sweden,residing at Stockholm, Sweden, have invented certain new'and usefulImprovements in Reaping Machines, (for which I have secured LettersPatent in England, No. 9,944, dated August 21, 1885; in France, No.175,678, dated April 22, 1885; in Germany7 No. 36,27 3, dated September8,1885; in Sweden,No. 197, dated June 3,1885; in Norway, No. 307, datedDecemberV 31, 1885; andl in Finland, No. 250, dated November 26,1885,)of which the following is a specification.

My invention consists in certain combinations herereinafter specified bythe claims, involving, among other devices, the reel or ily and thedropper or grain-depositing cradle. The reel by which the crop is laidtoward the cutters is driven from the aXle of the main wheels by a pairof beveled pinions, giving motion to an upright telescopically-jointedshaft with universal joints, and another pair of beveled pinions at theupper end of the shaft. One of these latter pinions is on the reel axisor shaft. The bearing for the reel is carried on a standard which is intwo parts, sliding oneon the other, and adjustable in height by means ofa rack and key. The key has two pins, serving as teeth for engaging therack-teeth, and is self-locking, thus dispensing with the employment ofdetent devices such as used when a rack and pinion are employed foradjusting the height of the standard. The standard is jointed to theshoe or inner divider ofthe nger-bar, and is held upright when in use bya stay or strut, and is locked by means of an eccentric, which sets thestrut down fast against aprojection on the shoe. The armsof the reel areconnected by cords, which serve as beaters. The reel is so connectedwith its axis that it can be released and turned at right angles theretofor the purpose of reducing the space occupied by the machine when outof use or arranged for travcling. The crop as it is cutis received uponan inclined dropper-platform or cradle consisting of parallel bars Xedto the under side of a cross-bar, which is pivotally supported behindthe finger-bar. The cradle is supported byibeing connected by way of alink-bar with the longer arm of abell-crank lever. A spring connectedwith the shorter arm ofthe lever operates to raise the cradle. Thecradle is moved to deposit the grain by atreadle,to which a partialrotary motion is imparted by the foot. An arm or link fixed-at one endto the treadle and connected by a link with the shorter arm of thebell-crank lever transmits the movement of the treadle to this lever,and so causes the cradle to descend at the proper time. When the cradleis up,the j oi nt connecting the treadle arm or link Xed to the treadlewith the link passing to the bell-crank-lever is slightly beneath theline of thrust, and is prevented from further descent by a stop, thecradle being thus supported independentlyof thespring. In machines inwhich the height of cut is adjustable a double joint is provided inattaching the reel-supportingn standard at its lower end to the shoe togive'the requisite freedom of movement, and a stay is provided passingfrom near the top of the standard to the draftshafts. wheel of thefinger-bar is at the rear end of the shoe instead of at its front end.

In the accompanying drawings, Figure 1 represents a reaping-machine inplan arranged for work. Fig. 2 is a side view, partly in section, of thesame. Fig. 3pb is a front view of the machine arranged for transport.Fig. 3 represents the attaching-screw of the reel. Fig. 3c is atransverse section of the telescopic shaft through which the reel isdriven. Fig. el.n is a section on the line a b of Fig. 2. Fig. 4* is aside View of the key for the adjustingrack. Fig. 5 is a section on theline c dof Fig. 2. Fig. 6'LL is a front View of the lower part of thestandard. Fig. 6b is a section taken on the dotted line g h, Fig. 6a.Figs. 7 and 8 represent an arrangement of mechanism employed when thegrain-depositing apparatus is applied to a reaping-machine withstubbleregulating apparatus, with the finger-bar pivoted to rock aboutthe center of asupportingwheel situated behind it, instead of in frontof it, as seen by the preceding figures. Fig.

In such machines the supporting- 7 is a front view of the reel standardsupported on the shoe or inner divider. Fig. 8 is a side View of thesame.

The grain-depositing apparatus consists of two main parts, the reel andthe cradle or dropper-platform, with its treadle mechanism.

The reel is put in motion in the following manner: The drivingratchet onthe right side of the machine, viewed from behind, is on the inner sideprovided with a conical pinion, .1, gearing with a corresponding pinion,2, on a shaft which runs in a bearing, 3. This shaft is, by means of auniversal coupling, 4, connected with the hollow shaft 5, which receivesthe inner shaft, 6. Parts 5 and 6 are connected bya groove and featherin the manner shown by Fig. 3. Another universal coupling, 7, connectsthe shaft 6 with the conical gearing S and the axis 9 of the reel. Theaxis 9 is supported by the bearings 10, projecting from and casttogether with the rack-bar 11. The bar 11 is able to slide upon thestandard 12, mounted on the inner shoe of the fingerbar. The rack ismade at pleasure to rise or lower by means of a key, 13, which serves tomaintain the rack at the height to which it is set. The standard 12 islocked in its place and made to stand erect upon the finger-bar by meansof the stay 11 and its strut 15, so that if, for instance, a stone orother like obstruction raises the finger-bar at the outer end the shaftof the reel nevertheless remains parallel with the linger-bar. The reel16 is provided with two pairs of arms, which at their outer ends areconnected by cords or like flexible connections 16.

The cradle, with the treadle mechanism, works in the following manner:The cradle 17 has its outer pivot, 18, supported in the strawdivider 19,which in its turn is supported upon the outerfngcr, 20, of thefinger-bar and upon the attachment 21. The inner pivot, 22, is supportedby an ear or bearing on the shoe. Against the inner pivot of thecradle,and parallel with the bars of which it is composed, there isfixed a bar, 23, on which a vertical guard, 24, is pivoted atits loweredge. Near the lower edge of this guard is fixed on a pivot a link-bar,25, and the opposite end of this link-bar isjointed to the bell-cranklever 26, which has its fulcrum on a bearing, 27, and maintains thecradle at a suitable angle to the finger bar. The lever 26 is supportedby means of a spring, 28, one end of which is secured to the short armof the bell-crank lever and the other to the stay 29 of thedraft-shafts. The treadle mechanism consists of the link 30, projectingfrom the short arm of the bell-crank lever,and the intermediate link,31, jointed at one end to it and xed at its opposite end to the treadle32, which latter is pivoted on the treadle attachment 33. A socket, 56,formed with the treadle and projecting in a forward direction from itspivot, serves to receive the rear end of the link 31 and tixedly connectit ment of the treadle,eannot fall to the ground,

whatever the weight of the grain collected upon it, because when thecradle is raised the joint between the links 3() and 31 is flexeddownward slightly beneath the line drawn through the centers of thefrontend of the link 30 and the rear end of the link 31, too greatdownward movement of the joint being prevented by a stop formed by thearm 5i, )rojecting downward from thejoint and bearing against thedraft-bar 55, to which the shafts are attached. Obviously the point ofjunction betweenthelinks,constitutingatoggle-likeconnection between thetreadle and thebell-crank lever, must first be raised slightly by meansof the treadle before the cradle can move automatically by upwardflexure of thcsaid toggle-like connection.

The rack 11 of the reel-standard always remains at the desired heightunless put in motion by operating the key 13. This self-lockingoperation of the key is due to the fact that its pins a and b are onopposite sides of the center of motion. The weight of the rack, it willbe seen, is supported by the pins, and the pressure upon the pins tendsto rotate the key in the same way that a pinion having cont-iguous teethwould be rotated, and such a rotation is obviously impossible frompressure upon the pins. Vhen, however, the key is turned by hand to theright or to the left, according to the direction it is desired to movethe rack, adjustment is rendered easy. The key has suitable bearing, 12,in the upper end of the standard 12. The strut 14 of the standard 12operates to render the standard fast with the finger-bar while themachine is at work. The lock-piece 15 of the strut is by its pivot 15lconnected to the standard 011 one side thereof, and on the other sideofthe standard the pivot is provided with an eccentric-pin, 15", onwhich the strut 14 is secured. XVhen the lock-piece 15 is broughtupward, its pivot 15 turns in the standard 12 and the eccentric-pin 15"rises, thereby lifting the strut 14 from the shoe. On the otherhand,when the lock-piece 15 is turned downward, the strut is pressedagainst the shoe, as seen in Fig. 6, and the standard is locked fastwith the finger-bar. When the standard is released, it is free to turnabout the joint-pin 53 at its lower end, and the apparatus may be foldedfor transport, as represented in Fig. 3. The lock-piece 15 then servesto support the standard, as the drawings indicate. When thegrain-depositing cradle is lowered, the grain passes from the cradle tothe ground, owing partly to its weight and partly to the aid receivedfrom the stubble, as is wellunderstood. The cradle when clear of thegrain is raised by the spring 28 and by the driver .the screw.

by means of the treadle, as will be readily understood. The socket ofthe reel, or that part of it which receives the axis 9, is forked, beingformed with two parallel sides, Fig. 1, between which the squaredprojecting end of the reel-shaft 9 is received. VThe shaft 9 terminatesin a peg, 38, and this enters a corresponding recess in the socket ofthe reel between the two parallel sides of the fork. The shaft 9 has ahole through it to receive the screw 37, and the forked socket has alsooblong slots (see dotted lines, Fig. 1) in its opposite sidescorresponding with each other for the passage of The screw 37 has ashoulder, 59, which enters and fills one of the oblong slots of theforked socket, and so locks the socket upon its shaft.

For transporting the reaping-machine the apparatus is folded up'in thefollowing manner: The reel` is raised to its highest position, the strut14 of the standard is removed from the shoe, and the fingerbar is raisedin the usual manner--that is, first or partially by means of its lever34, (the lever has the ordinary rocking sheave and liftingchainconnecting it with the coupling-frame 57,) so that the pawl of the leverenters the second notch of the segmentrack 35, and then directly byhand. The cutting apparatus, when thus folded, is secured by means ofthe knife-stay 36. This stay has jointed connection at its innerend'with the draft-bar 55, is bent and shouldered at and near its outerend, and slotted at 36L at its bent outer end to receive the key 58after this end has been passed through a hole in the ngerbar. Thefinger-bar is thus held between the key and shoulder of the stay. Theattachment-screw 37of the reel is next loosened sufficiently to permitthe shoulder 59 adjacent to its head to escape from the oblong hole inthe socket of the reel. The reel is then drawn outward to clear therecess at the junction of the inclined arms 16 fromthe peg 38,formed atthe outer end of the reelshaft, and the reel then folds down, as shownin Fig. 3, after which the screw 37 is again tightened.

By inspection of Figs.'1, 2, and 3au it will be understood that theguard 24 does not fold with the cutting apparatus and platform, butremains vertical, or nearly so, because of its jointed connection withthe bar 23. The slight upward and inward movements imparted to the guardin folding the parts'are not sufficient to strain or materially alterthe positions of the treadle mechanism and its connections v with theguard.

pivoted to rock about the axis of the supporting-wheel 40, which, asmodified, is in rear of the fmgerbar, and the reel-standard 39 has adouble joint-connection with the shoe in the following way: AA foot, 41,is pivoted at its lower end by a pivot-bolt passing through its forksand connecting it with lugs formed with the shoe. A pivotbolt, 42, atright angles to the bolt securing the lower end of the foot connectsthis foot above with the standard. Provision is thus made for the properrocking of the standard. The standard is provided with a stay, 43, Figs.1 and 8, engaging at one end with the pivot-eye 44 at the top of thestandard, and at its opposite end the stay is suit- Y ably'secured tothe shafts, (or to the inner end of the stay-bar 29 thereof,) by meansof theattachment 45. If the height of cut be altered by rocking thefinger-bar, the reel neverthe' less retains its position with respect tothe finger-bar, because of the above-described counections between thestandard and shoe and the standard and the shafts. I

To rigidly connect the foot of thestandard with the shoe, the followingdevices are ernployed: VvThe foot 41 is provided with an upwardprojection, 60, widened out at its upper end, where the standard bearsagainst it, so that throughout kthe limited movement irnparted to thestandard when moving about its pivot-bolt 42 the standard will bearagainst this widened upper end of the foot. Acurved lock-piece, 47, isengaged at its bent lower end with a socket in the point of the shoe,and its upper end is bent upwardly and connected by a pivotbolt, 61,with the upward extension ofthe foot. A strut, 46, bearing at its lowerend against a projection upon the shoe, is at its opposite endshouldered and lapped under the lock-piece 47 below its pivoted boltl. Apivot-bolt, 62, connects the upper end of the strut with the lock-piece,and the shoulder of the strut abuts against the lock-piece. be seen thatby these devices the foot may be rigidly secured upon the shoe. devicesform atoggle-like connection between the shoe and the foot of thestandard.

I claim- 1. The combination of the reel having the slotted forkedsocket, the reel-shaft received between the forks of the socket, and theattaching-screw passing through the reel-shaft and through the slots inthe reel-socket, and provided With the shoulder for engagement with oneof the slots in the reel-socket, substantially as and for the purposeset forth.
